Peer-graded Assignment: R Markdown Presentation & Plotly

Overview

In this project, we will create a web page presentation using R Markdown that features a plot created with Plotly. We’ll host our webpage on either GitHub Pages, RPubs, or NeoCities.

Our webpage must contain the date that we created the document, and it must contain a plot created with Plotly.

Relationship Between the Local Temperature and The Ice Cream Consumption in the US

Based on the graph above, the temperature in the locals’ area is correlated to the amount of their ice cream consumptions.
